When does the free hit come into play in T 20 cricket?

Question

Another new concept of T-20 cricket is the free-hit, where in a batsman gets a change to have a free hit at the ball knowing that he cannot be given out. When does the free-hit come into play?

Answer 1

Whenever a bowler bowls a no ball, a penalty of one run is awarded to the batting side and the batsman gets an extra delivery. However in T-20 cricket apart from this penalty, a free hit is given in the next delivery. So if a foot fault no-ball occurs, then the next ball is a free hit for the batsman, he can play any stroke and will not be given out (except run out).
Though this rule is loaded in favour of the batsman, in the opinion of great bowlers like Ian Bishop, this rule has helped bowlers to be more disciplined and control the number of no-balls. After the success of this rule in T-20 cricket, it has been extended to the 50 overs version. However, there is no free hit in test cricket.
