22 . Bxa6

Bxa6 captures a pawn and adds support for a b-file invasion. Black can contest that invasion with the rook and later capture White’s a-pawn. The point is to compare the activity and the supported entry squares, not merely the first pawn gain. Trace the bishop’s diagonal before judging a rook capture on b7.

Rhb1 doubles the rooks on the b-file. The doubled rooks force Black to account for pressure near the king, but the game later changes its focus. Watch how White keeps useful central squares while Black defends the file. An attacking setup should be reassessed when the defender’s pieces reorganize.

Bh3 gives the bishop a diagonal toward the central pawn. The move prepares a capture while the white rook stands on d6. Black can attack that rook with the knight, so the next calculation must include the pawn recaptures as well as the bishop. Compare the two threats on the actual board.

33 . Bxe6

Bxe6 begins a sequence that creates a dangerous passed pawn. The recorded knight capture on d6 is answered by the pawn, and after another bishop capture that pawn takes a rook on e7. Recount the material at the end of this sequence and inspect the remaining promotion threats. The combination depends on the pawn’s route, not only on the first capture.
