Subject: BT2630 questions

I've been looking at the BT2630 test suite, which I run routinely.

One of the positions is #26:

2r3k1/pbr1q2p/1p2pnp1/3p4/3P1P2/1P1BR3/PB1Q2PP/5RK1 w - - bm f5; id "test 26";

Is f5 really a decisive move here? Currently my program likes g3
after searching nearly 200 million nodes. At earlier plies it
selected Re5. They all look pretty reasonable to me. f5 looks
good : but is it positionally better, or does White get material
or a decisive attack?

Another one that I'm not passing at present is #13:

2bq3k/2p4p/p2p4/7P/1nBPPQP1/r1p5/8/1K1R2R1 b - - bm Be6; id "test 13";

I used to get Be6, but now on a faster machine it eventually
switches back to c2+ at ply 12 and holds it.
