[D]2br3r/p5k1/3b4/2pPp1pq/Pp2Q1PP/4NP2/1PB5/R2R2K1 b - - 0 1
Best move Qxh4 with a close game. Position is from an OTB game.
[D]r2q2k1/pp4b1/3np2r/3p1p2/3P1P2/2N1PBK1/PP5Q/2R4R w - - 0 1
Best move Qxh6. Finding it is not all that impossible. The thing is that I had
to see it a couple of moves earlier.
[D]r4rk1/5pp1/pq3n1p/5P2/1Q1ppP2/P7/1PP1B1PP/R3K2R b KQ - 0 1
Best move Qa7. Second best Qxb4. Team game on FICS.
[D]8/4k3/1p6/p1pPPp1p/2P1p3/4P2P/P1K5/8 b - - 0 1
[D]8/4k3/1p6/p1pPPp2/2P1p2p/4P2P/P1K5/8 w - - 0 1
[D]8/4k3/1p6/p1pPP1p1/2P1p2p/4P2P/P1K5/8 w - - 0 1
Analysis of the REBEL-Web game. And variations of the position. All drawn. The
eval of programs are usually way off.
[D]r6r/4pk2/ppp3pB/q3P3/2pP4/1bN3Q1/1R4P1/6K1 w - - 0 33
Best move e6+. How long to play. And does it see that black is worse? Game
against GT.
[D]r2k3r/8/ppQ3pB/q7/2pP4/1bN5/6P1/6K1 w - - 0 1
How long to find the directly winning Qf6? Or to show a winning score?
[D]rn2kb1r/1b1pnpp1/1B6/1p1RP2p/1qp2N2/2N2P2/PP2Q1PP/2K2B1R b kq - 0 1
Best move Qxc3+!
[D]r1bq1rk1/1p2b1pp/p1np4/8/2P1P1n1/N1NB2B1/PP3P1P/R2QK2R w KQ - 0 1
To survive white needs to play O-O.
[D]r1bq1rk1/1p2b1pp/p1np4/8/2P1P1n1/N1N3B1/PP2BP1P/R2QK2R b KQ - 0 1
Nxf2!
[D]r1bq1r1k/1p2b1pp/p1np4/3Q4/2P1P3/N1N3B1/PP2Bn1P/R3K2R w KQ - 0 1
Only move Rf1!
[D]r1bq1r1k/1p2b1pp/p1np4/3Q4/2P1P3/N1N5/PP2BB1P/R3K2R b KQ - 0 1
Both Nb4! and Rxf2! wins. How is the PV? Often the programs cant resist a check
on b6.
[D]r1bq1r1k/1p2b1pp/p2p4/7Q/1nP1P3/N1N5/PP2BB1P/R3K2R b KQ - 0 1
Best is Rxf2!
[D]r2qkb1r/pb3p1p/1pp1p1pB/8/3PB1Q1/6P1/PPP2P1P/R3R1K1 w kq - 0 1
How long to play Bxg6!
[D]5k2/p3pp1p/1p1p2p1/2r5/PPP1R2P/6P1/4KP2/8 b - - 0 1
Easiest win is Re5!
[D]r5k1/5p1p/2p1pn1b/Pq1p1p2/3P1N2/2B1QPP1/4P2P/R5K1 w - - 0 1
Qd3 makes blacks defence well nigh impossible.
[D]1R6/3k3p/r1p1ppn1/P1Bp1p2/3P1P2/3P1P2/3K3P/8 w - - 0 1
Bb6! is an evil move. Bb4?! is the most convoluted way to win.
[D]r2r2k1/pp1n1ppp/2bppq2/8/4PP2/2NB4/PPP3PP/3RQR1K w - - 0 1
b4 or black is better.

A couple of eval testers:
[D]1k6/p7/P7/8/8/5K1B/8/8 w - - 0 1
Draw!
[D]3k4/p1p5/P1P5/8/8/5K1B/8/8 w - - 0 1
Draw!!
[D]5k2/p1p1p3/P1P1P3/7B/8/5K2/8/8 w - - 0 1
Loss ;) Remarkable how the actual geometry of the chessboard influences play.
[D]rq3bnr/pp1kpppp/8/1QpNp3/8/8/PPPP1PPP/R1B1K2R b KQ - 0 1
3 0 game on FICS. Avoid Kd6 and Ke6. Not that it is an easy win but on principle
alone.
[D]5k2/1q4bQ/5p1p/p1p1pPpP/2PpP1P1/Pp1P4/1P5K/5B2 b - - 0 1
Realize the winning nature of blacks position.
[D]rn2kbnr/pp3ppp/1q2p3/2ppPb2/3P1B2/2N2N2/PPP1BPPP/R2QK2R b KQkq - 0 1
Avoid the terrible Qxb2.
