Apparently some current chess programs/engines do choose to play Be4. Kasparov's concern revolved around as to how Deep Blue could prefer this move (after about 15 mins thinking time) over the clear material winning move Qb6. Also after playing this and other good moves why did Deep Blue allow Kasparov a simple draw by perpetual check? (which however he sadly missed). It was this apparent inconsistancy that bugged Kasparov throughout the rest of the match and made him believe that there had been some human intervention. Terry
