Here's game 5 of the welcome tournament. Rebel10 began with powerful play in a rather calm variation: the so called 'Moscow variation' of the Semi-Slav was already played like that (with ...h6 and ...Bd6) by Gruenfeld-Janovsky, Semmering 1926. Black gives white a small space and development advantage while having a very solid, well defensable position. 9...Rd8 was a novelty played out of book by Genius, and from then on both programs had to find their own moves. White's move e4 is thematic in this opening, despite already having played e3. Rebel did not hesitate to play with an isolated pawn to open the position and get pressure. What surprised me most in this phase of the game: it made excellent use of this pawn by dynamic play, sacrificing the pawn for some moments in move 14 (d5!) like a good human player would do, while using the open lines for dynamic pressure and piece attacks on the vulnarable, not yet fully developed black position. After move 20 white had both the open c- and e-file plus a bishop retired to b1, anytime being able to build a battery with the white queen to aim at h7. The pawn was won back in move 20, and after 23.g3 black was in big trouble. Genius solved this trouble, like Petrosian would have done it (though in this case hardly having better choices): with an exchange sacrifice, thus getting the growing pressure off the black position. The resulting endgame meant big drawing chances for black, finally winning a weak black pawn back in move 57, while white was desperately trying to get back some initiative with rook against bishop. But after the exchange of the only remaining queenside pawns there was no chance left for white to get more than a draw: his isolated kingside pawns could not be used for any attack, and the bishop in this position (unlike in the previous game against Mchess) had no problems to move, without leaving the pawns unprotected. In the final position, when I decided this to be a draw (could have done so earlier), black could even afford to lose the f6 pawn, and still build an unattackable fortress with Bf5, Pg6,h5, without problems for the black king. Nice game: excellent positional attack from Rebel, excellent exchange sacrifice defence by Gernius, ending in a draw.
