pushing out the fielder on the point boundary

Graeme Smith has lost this (glorious, fascinating, wonderfully typically gripping) 2nd Test at Port Elizabeth simply by pushing out the fielder on the point boundary. A South African team with Ntini and Pollock bowling like gods should not lose, get this, Pakistan chase 191 and are 5/92 just after lunch with Yousuf and Inzi just gone after marvellous pressure bowling and fielding, winning those stories, so game over, no? with no Pakistan tail and another couple overs from this pair just so tight and no runs in sight, till Pollock drops just one short, over 41.3 check it out by scrolling to the bottom of the cricinfo match commentary page, right, before that ball it's 5/96 and the Africans are winning all up for sure Inzi gone Yousuf gone go home 2-0 thank you Smith mouthing off as ever from slip, don't get me started, ok, then the dumb defensive skip thinks 'O! Polly's getting tired! He's so old! Let's push the man back even though we're about to take the 6th wicket and run through the tail and win!' and next ball - look at the commentary, it's true, as a tedious bowler I know the pain - there's one, straight to deep point, wouldn't have been a glimmer of a run without the guy pushed back, and then next ball Kamran Akmal slices (a beauty) through the empty 3rd slip, then gets 1 off the last ball, and it's all on, and just look at the next few overs how many go through backward point for 1s and a couple 2s and suddenly they need not 99 but 69, then *more* go through backward point until Akmal stops messing and slicing and plays some glorious pull shots to go with Younis's matchwinning dig. And how could Smith not bring Polly back instead of gruesome Nel for the 51st or 53rd or even 55th over when they still needed 31?? The worst captaincy I've seen for a while.
