{it appears that the pawn did not change its column (axb3xa4) and would therefore have hindered the passage of the bK, which is therefore "enlarged". But then he had to pass by h3-g2-f1. In order for the wK to let him pass, the latter must be enlarged too. But Pf2 & h2 forbid him diagonal steps. He must therefore have castled. He is thus totally immobilized. Note that 2.Qd3+ does not check}
